Cutting multiple cast components from their runners and risers.
One of the traditional methods for cutting off cast components is to use an abrasive cutting disc mounted in a circular saw bench. In a typical day at one foundry the operator of such a machine could spend up to 3 hours exposed to vibration magnitudes of up to 5 m/s2. The operation is also very noisy and there is potential risk of injury from contact with the exposed cutting disc.
Two fully-enclosed, semi-automatic cut-off machines were bought, principally to improve quality and efficiency. The multiple castings are clamped in rotating fixtures, trunnion mounted, and cut off with an abrasive disc.
